TIRE PUMP Filed Nov. 5, 1928 2 Sheets-Sheet 2 ATTORNEY Patented' ec. 9, 1930 REUBEN B. JORDAN, OF POPLARVILLE, MISSSSIPPI TIRE PUMP i Application led November 5,-1928. `Serial No. 317,266.

rlhis invention relates to pumps especially t adapted for inflating pneumatic tires, an object being to provide a pump which is simple,

cheap, compact and durable in construction, and which may be connected with the engine of an automobile for its operation.

Another object of the invention is the provision of means for connecting the pump with the engine, wherebyv a slight pressure against the pump will hold the latter in operative position, while release of pressure will disengage the pump.

Another object of the invention is the provision of a pump of the above character ih l5 which the operating gears are housed to pro- V tect the user; novel means being also provided for quickly adjusting the pump to the height of the engine crank shaft for connection with the latter.

With the above and other objects in view, the invention further includes the following novel features' and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawings and 25 pointed out in the appended claims.

ln the drawings Y Figure lis an elevation of a pump constructed in accordance with the invention.

Figure 2 is a sectional view taken substantially on the line 2-2 of Figurel 3. j Figure t is a fragmentary rear elevation showing a portion of the frame and its adjustable supporting leg.

Referring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference character 10 indicates a frame which may be solid or open as desired. This frame has extending therefrom a post 11 and pivotally mounted upon this 40 post by means of bands 12 is a pump cylinder 13. Thisk cylinder is provided with a head 14C having air escape ports 15 therein, and operatino' through this head is a rod 16 upon the inner end of which is mounted a piston 17.

Rotatably mounted in the frame is a drive shaft which includes an inner section 18 and an outer section 19, the latter being pivotally connected to the outer end of the inner section as shown at 20. Secured upon this drive shaft is a pinion 21 which engages and drives an internal ring vgear 22, the latter being fast upon a stub shaft 23 having a bearing in the frame 10. rThe gear 22 encloses and forms a housing for the pinion 21 and the teeth of the said gear so that this gear and pinion may be properly lubricated without danger of soiling the hands and clothing of the user. The outer end of the rod 16 is pivotally connected with the housing of the ring gear 22 as shown at so that operation of the ring gear will reciprocate the piston 17.

The cylinder 13 is provided with a check valve controlled air escape port 25 from which extends an air hose 26 whose outer end is provided with a suitable connection 27 whereby air may be introduced into the tube of a tire. u Y rlhe-outer end lof the pivoted section 19 of the drive shaft is provided with'oppositely extending pins 28and these pins are adapted to be received ywithin Ythe usual notches 29 provided inthe end of the crank shaft-.30 of an automobile engine after'the manner'of the usual hand crank.

In order to properly adjust the height of the pump to the height of the shaft 30 the frame 10 is pro-vided with oppositely located guides 31 and slidinglymounted within these guides is a leg 32 having a base or foot 33 at its lower end. This leg carries Ya pivotally mountedk dog 34 which is adapted to engage teeth 35 provided along the inner face of the frame 10. By reference to FigureV 3 of the drawings it will be seen that the heightof the? frame may be quickly adjusted'byadjusting the leg 32, the dog 34 holding the frames in proper adjusted position.

By rslight inward pressure against the pump, the pivoted section 19 of the drive shaft will beheld in proper operative engagement with the crank shaft 80 of the engine so that the pump will continue to operate as long as the engine is running and pressure is brought to bear. Release of pressure will cause the drive shaft section 19 to be immediately disengaged from the engine crank shaft and operation of the pump will stop.

The frame may be provided with a bail or handle 36 which is pivotally connected to the frame as shown at 37 for convenience in handling. When not in use the bail may be folded against the pump and the leg moved inward so that the pump may be stored Within the tool compartment of the automobile.

5 The invention is susceptible of various changes in its forni, proportions and minor details of construction and the right is herein reserved to make such changes as properly fall Within the scope of the appended claims.

Having described the invention What is claimed is: I

1. In a device of the character described, a base including a substantially fiat standard rising therefrom, a rectangular plate including a reduced channel like lower portion slid* ably mounted upon the standard, a pivoted handle carried by said plate whereby thelatter can be adjusted vertically on the standard, said plate having notches formed in the rear Wall thereof, a pivoted dog carried by the standard and cooperating With the notches to hold the plate in a given position, a post projecting horizontally from the front face of the plate, a cylinder supported on said post, a piston operating Within the cylinder, a piston rod, and means supported by the plate for reciprocating said piston rod and including a drive shaft arranged at one side of the plate. f f v 2. Inra device ofthe character described,

a base including a vertically disposed standard, a rectangular plate including a reduced channel like portion slidably mounted upon the standard, a handle carried by the plate for adjusting the latter upon said standard, means for holding the plate fixed in a given position, a post projecting horizontally from the plate, a cylinder supported by said post, a piston operating Within they cylinder and including apiston rod, a drive shaft journaled on the plate and including pivotally connected sections, a pinion carried by the drive shaft and arranged at one side of the plate, a ring gear j ournaled on the plate and meshing With said pinion and constituting a `housing for the latter, and means connecting the piston rod with the ring gear to actuate the piston incident to the rotation of the drive shaft. In testimony whereof I aHiX my signature. REUBEN B. JORDAN.
